Patented Jan. 14. 1919.

Application filed March 23, 1918. SeriaINo. 224,178.

To all whom/it may concern Be it known that we. EDWARD B. Hess and LEWIS C. MYERS, citizens of the United States of America, and residents of the borough of Brooklyn, in the city of New York, county of Kings, and'State of New York, have invented certain new and useful Improvements in Typeriting Machines, of which the following is a specification.

The present invention relates generally to typewriting machines and hasmore particularly reference to improved margin controlling devices, line locking and releasing mechanism, and bell ringing mechanism.

This invention is an improvement over the structures shown in applications filed by us J uly 13, 1917 and Oct. 27, 1917 and respectiveljv numbered serially 180,261 and 198,775 in which visible margin controlling devices in front of the platen, and above and inrear of the forwardly recumbent type bars,

are used. I

In the above mentioned applications there are disclosed margin rails in front of the platen and on both sides of the printing center so arranged as to afl'ord space between them for the passage of the type bars to the printing center together with complementary stop means between the transversely movable platenand the margin rails arranged so that the right hand margin controlling devices limit the movement of the platen in a left hand direction and the left hand margin controlling devices limit the movement of the platen in a right hand direction. As there shown, the left hand margin rail is rigid and has a stop that cooperates with a stop block at the left hand side of the platen while the right hand margin rail is mounted so as to partake of a rocking movement and carries a stop composed of two dogs with which engage a stop block. on the right hand end of the platen. that acts to eticct a partial rocking of the margin rail bv engagement \viti the first dog and a more complete rocking motion of the margin rail by its engagement with the second dog. the hell ringing device being operated by the more limited movement of the margin rail while the line lock: means are operated on the more complete rocking ll'lOVGIllOl'lb oi the margin rail. he stop block carrledby the platen consists oftwo members, spaced apart vertically, that cotiperate in either lower case or shifted position with the transversely spaced dogs of the stopmember carried by the margin rail. In that device there is also provided suitable connecting means between the line lock, the bell ringing mechanism and the. margin rail. the parts being so arranged that there isa releasable connection that permits the-line locking means and the margin rail to'be restored separately while. at the same of the complementary stop elements between the right hand margin rail and the platen:

and also to means for making connections between the. margin rail. the line locking means and the bell ringing device as well as .to the methods of moun'tingthe margin rail itsel'h'a rocking and a sliding movement being imparted to the margin rail insteaci' of two rocking movements of ditt'erent amplitude. as in the Previous applications.

One of the main features of the invention resides in so mounting the margin rail that it has both a rocking and a sliding movement, and 'in eti ecting line looking b v means of the sliding movement of the margin rail. and in making possible the release of the line locking means bv rock ng the rail so as to move the members of the stop element out of each others path.

Another feature of the invention resides in imparting a rocking movement to the marginrail for efiectiiu: boll ringing and a sliding movement to the rail for (fleeting line locking and. in addition thereto. operut'iug: means. independent of the platen. for rocking the margin rail to admit of the re lease of the line locking means. it will thus be observed. thatrockirg ol the nmrgiu rail servos two purposes. a". c. to operate the bell lease of the line locking means.

7 The invention is embodied in the Another feature of the invention resides in the interconnection between the actuating member, or margin rail, and the line locking means whereby the parts are connected for movement in response to endwise movement of the margin rail at all times, while admitting of an the margin rail.to a line locking means and also for the purpose of bell ringing.

The complementary stop means between the other, the taper surface on the right hand dog presenting the lowest portion' of its taper to the advancing stop block so as to rock the margin rail under the influence of the advance of said block and permit the rail to be restored a ruptly after being rocked into its highest position; said secondstop dog presenting an abrupt abutment surface to the advancing stop block so as to transmit the endwise movement of the platen to the margin rail. The taper surface of said second stop dog is so arranged that its highest point is adjacent to the abrupt abutment surface so that, when the parts are released, the margin rail will be restored gradually and without effecting a second ringing of the bell.

Other features of constructionwill appear as the specification proceeds.

1 indicates the general frame-work of the machine in which is mounted the carriage raceway'Q supporting the carriage 3 and provided with case shifting mechanism indicated by themember 4 so that the carriage and its support may be raised or lowered in a manner well understood in the art. The shift mechanism employed is that of the well known Royal typewriter, such as is described in Patent N 0. 1,227,438. Mounted in the carriage 3 is a platen 5 of any suitable construction and provided .with a suitable line space advancing mechanism 6 in the usual manner. 7 indicates a segment on which are pivotally supported type bars 8 normally occupying a forwardly recumbent position with their free ends resting on a head rest 9located near the forward end of the machine. 10 indicates the key levers pivotally supported at 11 in a suitable bearing and connected by means of a vertical link 12 to'a front link 13 connected to the type 'bar by means of a link 14. To link '14 is secured a bar or link 15, the rear end of which is bent to bar 16, link 15 being provided with a spring 17, the rear end of which is connected with an adjustable rocking frame 18 and the front endof which is secured to a member 19 carried, by link- 14. It will be understood that all the type bars, when actuated, move to'a common printing point or center; Adja engage a universal two converging members suitably mounted left hand side of the common printing .cen-

' spools 26.

by means of a bracket 21 on a stationary part of the machine. Mounted to move with vthe carriage raceway 2 so as'to partake of the case shifting movement imparted thereto, is a ribbon vibrator 22, a front card guide 23 and its scale 24. 7 These elements are also located adjacent to the printing point and are intermediate'the type bar guide and the platen. Inolosing the upper part of the machine are, dust sheds 25 carrying ribbon 27 indicatesa margin, rail located on the ter, and 28 indicates another margin rail located on'the right hand side of the commonprinting center. These margin rails are conveniently supported, in this instance, on-top of dust sheds 25 in front of a vertical line and below a horizontal line drawn through the axis of the platen below the normal position occupied by the ribbon vi-- brat-or and in front thereof, and also in front of the card guide and its scale. In fact, the margin rails, as here shown, are located in front of a vertical line tangent to the front face of the platen and below a horizontal line tangent to the underside of the platen. It will also be noted that the margin rails are above the series of type bars and over, and substantially in line with, the pivots of said type bars. In this case, therefore,, the dust'sheds also constitute supports in front I of and below the platen and above a series of type bars for the margin rails.

Associated with the right hand margin. rail is a stop element 29 adjustably mounted thereon and -'a stop element or block 30 mounted on the carriage. -Said right hand margin rail isprovided with pivot-extensions 31 thatproject into suitable bi'lshings.

32 in a stationary part of the frame work in such manner that margin rail. 28 has both a rocking" and a lengthwise sliding motion.

Extending from the lower side of ,rail 28 is a dependent controlling member 33 and attachedat one end to said controlling mem her is a spring 37, the other end of which is anchored on dust shed 25, said spring tending normally to maintain the righthand margin rail in normal position,that is to say, in its Ktreme position to the right, lengthwise, and in its lowered position with respect-to its rocking motion. The spring therefore serves a double purpose. as indithe downward movement of said line locking blade. Interposed. between the controlling member 33 and the member 43 are suitable connections, which in the present instance, take the following form. 45 indicates a vertically extending rock shaft located below the dust shed and adjacent to the right hand side of the machine, being carried in suitable brackets, as 46. Connected to the lower end of said rock shaft 4:5 is an arm 47 between which and the member 43 is in.-

terposed a link 48.

Secured to the upper end of rock shaft 45 is a bifurcated member 34 the outer end of which embraces controlsuitably attached to controlling member 33,

The stop member 29 is in the as shown,

form of a guide or carrying member 55 slidable upon the right hand margin-rail 28 and is provided with a spring-pressed pawl 56 adapted to engage in notches 57 of said rail. The particular construction here is that the carrying member .55 is provided with a pivot 58 for receiving cars 59 of pawl 56. 60 indicates a spring that presses against'the under side of ahandle portion 61 and normally urges said pawl 56 into engagement with one of the notches or'teeth 57 of the rail. The carrying member 55 of the'stop member is provided with two dogs or cam members 62 and 63 projecting inwardly toward the platen and spaced apart laterally, as shown. Said dogs are provided with taper or cam surfaces 62 and 63? which are inclined .in opposite directions away from each other. Dog 63 also has an abutment surface 63". The relation of the cams,

or dogs, 62, '63 is such that, when stop block 62 thereby tilting or rocking margin rail 28 without shifting it endwise. As soon as the member 30 has passed the high point of taper surface 62, an abrupt release of the margin rail from its rocked position and into its lowered position will be effected. Upon further advance of stop block 30 in a le'fthand direction, it will encounter abutment surface 63" thereby shitting margin rail 28 lengthwise in a left hand direction. The stop element 30, mounted to move with the carriage or platen, is provided with a latch 64 pivoted at 65 and having a coiled spring 66 that bears with one end against the latch 64 and with its other end against plate 67 of stop element 30. 68 indicates an "adjustable stop carried by plate 67 for variably limiting the effective action of spring gages.

' member 33. The effect the left and lat h 64 latch 64 Wlll engage withcam surface 62 thereby tilting margin rail 28 without effecting endwise movement thereof. As soon as latch 64 has passed beyond the high point of taper surface 62 margin rail 28 will be abruptly released thereby permitting spring 37 'to restore the parts to normal position. The rocking ofmargin rail 28 by means of latch 64 engaging the taper surface 62 will cause the parts to assume the position shown in Fig. 5 where,.it willbe seen, controlling member 33 is moved into an inclined position lifting bell hammer 54. It will be noted, that in assuming this position, the

member 33 is free to move through the bi furcated ortion of arm 34 of vertical shaft 45. On t e abrupt release of margin rail 28 by the .assage of latch 64 vover the hi h point 0 taper surface 62, gravity and t e action of s ring 37 will cause hammer 54 to descend quickly, thus sounding gong 52 and thereby informing the operator that the carriage 1s approaching the end of the line.

The position that the parts occupy at this time is indicated in Fig. 3. It is now impossible to manipulate the key levers to bring the type bars to the printing point and the' carriage has reached the end of its movement as determined by the position of margin stop 29. If, however, it is desired to release t e parts to admit of writing additional matter on the same line, the margin release rod49, having on its inner end the pusher 49,- is moved inwardly, as indicated in Fig. 5, being thus caused to engage controlling member 33 and thereby impart a rocking motion to margin railv 28 ofsuflicient amplitude to permit latch 64 topass over the high point of abutment member 63". "It will thus be seen, that the-rocking motion of the margin rail has two functions,

means of set screws 69 that pass .28 to have a one to ring the bell and the other to release the complementary stop elements from each other when in the position described. As soon as the parts have been thus released, the pull of spring 37 will cause margin rail retrograde lengthwise movement thereby avoiding the necessity of keeping themargin release rod depressed. It will be understood that the margin rail 28 in being rocked for the purpose of releasing the stop elements will have raised hammer 54 and, to prevent the gong from striking the bell a second time during the cycle of the machine, a taper surface 63 is provided which, as the carriage continues its movement in a left hand direction, gradually permits spring 37 to restore the margin rail to normal position so far as its rocking movement is concerned. The descent of hammer 54 is-therefore so gradual that no sound is heard when it finally reaches bell 52. vanced to theleft until the usual stop elements, not shown, come together. It is a characteristic feature of this constru tion that the connection between the line locking means and the margin rail isalways complete for the purpose of transmitting the I endwise motion of said margin rail to the The carriage may now, of course, be adso as to admit of a retrograde endwise movementof the margin rail and thereby permit the line lo k to restore itself. It will be observed that with the construction disclosed, it is immaterial whether the carriage is in its lower case position. as indicated in Fig. 5. or in its shifted position, as indicated in Fig. 6, since, in either event, latch 64 will en age in a manner nreviouslv described with dogs 62and 63. It will further be understood that, owing to latch 64, the carriage may be moved to the right past the cam members 62 and 63 without effecting a tilting movement of the margin rail and without displacing said margin rail member 76. slidably engaged on rail 27 and is provided with a stop dog 77 consisting, in

'ment of pin 81 with the end shown more particularly in Fig. 1, thereby effect, of an adjustable screw. 78, indicates' and with its other end on the carrying member 76. The pawl 78 is further provided with a handle or operating 1nember83, as shown. When the handle is depressed against the action of spring 82, the point of pawl 78 becomes disengaged from the notches in the margin rail 27', and simulta neously therewith, the carrying member is moved to the left so that pin 81 occupies a mid-p0sition in slot 80.. "When the pressure on handle 83 is released, the end of pawl 7 8 enters the notch in rail 27, the pin 81 meanwhile remaining substantially in its mid position in slot 80.. When thereafter the stop element 75 on the carriage engages the stop dog 77 as the carriage is moved to the right, the carrying member 76, and with it the dog 77, is moved to the right a distance equal, substantially, to one letter space, its position being determined by the engageof slot 80, as

bringing the carriage to the right t0 the ex treme limit of which the adjustment of the stops admits, The stop member 75 is slid ably mounted in the carriage 3 of the machine, in this instance, by means of slots 8% sliding on pins 85 attached to said carriage, Asp ring 86, anchored on the frame 3 and connected with the inner end of member 75,

normally urges said stop element 7 5 into its outermost position in the plane of stop dog 77. When the carriage is moved to the right, it will continue its movement until. the stop element 75 encounters stop dog 77.; but,

. when moving the carriage tothe left with the stop element 75 in a position between the printing point and the stop dog 77, said stop element will be caused to move rearwardly due to the fact that its outer end is beveled, I as indicated at 87 said bevel surface coming incontact with a corresponding bevel surface-88 carrledby stop element 74. 'In case it is desired to move the carriage in either direction without interference, stop element 75 may be withdrawn by engaging a handle portion 89 and moving the end of said stop element out of the plane 'of 74. v I

It will benoted that the left hand margin rail 27 is rigidly mounted on dust shed 25 and is therefore entirely different in its characteristics from. that of the right hand margin rail 28. Thereason for this will be apparent when it is understood that the left rail 28 will, if

hand margin control devices must register exactly; and their construction. therefore must be of such nature that so-called "banlting over willnot occur, This is especially necessary in view of the fact that when the carriage is moved by the line space leverto its initial position, times, retract the carriage with considerable force. It will be observed that, so far as the relation of the stop elements 7 1- and 7 5 is concerned, it is immaterial whether or not the carriage is shifted into lower or upper case position.

A characteristic feature of the invention is the scale indication used in connection with the margin rails. This scale indication may be adjacent to, or, more conveniently, upon the top surface of, the margin rails as shown. The scale indication on the left hand rail 27 begins with zero at the right hand end of the rail and is continued up to say the letter space thirty; or, as shown, by extending the margin rail beyond the general outline of the dust shed up to letter space 4C0- Similarly, the scale indication on the right hand the right hand margin rail is extended in the same manner, begin with forty-one and continue to such number as may be desired, say eighty; or, if the margin rails are made shorter, the intervening numbers, say from thirty-one to forty-nine may, from a practical point of view, be omitted, since the stop elements are really only intended as margin stops in the true' sense of the word.

The peculiar scale indication described is necessary when the stop elements are arranged as in the present case and. wherefull visibility of the margin scale indication is desired,

In operation, the stop elements 74: and 29 are adjusted to desired position. The carriage or platen is then moved to'the right, its transverse movement in that direction being limited by the left hand stop elements 74 and 7 5 but is unobstructed by stop elements 29 and 30 on the right hand side. The manipulation. of keys 10 now causes the carriage or platen to travel to the left until the stop elements 29 and 80 on the right hand sidelimits the movement to the left.
